JavaScript - Searching Text File With Javascript
Im trying to use javascript to search a text file. text file is like this...
1111111[TAB]Project Name[TAB]Application1 2222222[TAB]Project Name[TAB]Application2 Im trying to get the javascript to let a user search for number or project name, if found it displays all the info if found. application1 or application2 (whatever is in the 3rd area) The text file can also be seperated by commas, either way is fine. can anyone help with this. ? Similar TutorialsI've tried every combination I can think of, and I can't figure this out. According to me, if you type a name that matches one of the xml items' names into the box using the following code: Code: Name: <input type="text" id="nameInput"/>
<input type="button" onclick="searchLocations()" value="Search Locations"/>
function searchLocations() {
var input = document.getElementById('nameInput').value;
if (!input) {
alert("please enter a name");
} else {
for (var j = 0; j < gmarkers.length; j++) {
if (gmarkers[j].myname == input) {
gmarkers[j].show();
}
}
}
}
it should show the gmarker with that name... but nothing. If I leave it blank and hit the search button at least I get the alert, so something is working... any suggestions? Hello, I am building a web application that has quotes on it. I am planning on having all the quotes stored in a .txt file. A line space would separate the quotes. Example: "Blah Blah" "Idk what blah" "sure you do" Would this be using Javascript to pull the quotes from the txt file for use in my page be best? I need it to pull all the quotes. Reason for having it like this, I am also planning on having a random quote page where it just pulls 1 quote instead of showing all of them. I'm also open to other ideas here! David Faircloth Hello, i m new Javascript but knows basics of functions etc. ive created a website, which also has field to Submit Email addresses for newsletters.. Now, i have a TextBox (for users to write email addresses) and a Submit button in which i want to call a Javascipt script function which OnClick takes the value(email address) from the textbox and saves it to a .txt file on server. i think i am just missing a single line, the function name which will store the value.. i searched ovr the net but didnt find it.. plz help mee. Thankyou! Somebody had posted this query on how to read text files using JavaScript.......can't find that post now... Anyways, though it's not possible to read text-files using JavaScript it is possible to read XML files using it. Here is an XML based JavaScript Ticker http://www.dynamicdrive.com/dynamicindex2/xmlticker.htm It works only on browsers supporting XML (IE) Enjoy! hi, i want to create a extension for chrome using which i can save the current tab url in a text file. thanks sanjay Hi I have written the following code to read contents of a text file using FileReader object of HTML 5 for Google Chrome. Quote: <script> function handle_files(files) { var i; if (checkBrowser("Chrome")) { for (i = 0; i < files.length; i++) { file = files[i]; var reader = new FileReader(); ret = []; reader.onload = function (e) { console.log(e.target.result) } reader.onerror = function (stuff) { console.log("error", stuff) console.log(stuff.getMessage()) } text = reader.readAsText(file[i]); alert(text); } } } </script> ---------------------- <input type="file" multiple="multiple" onchange="handle_files(this.files)"> Unfortunately, the variable text always displays as undefined. Everything above the line text = reader.readAsText(file[0]); works fine. How can I fix it?. Or is there any other solution to read a text file using HTML5/JavaScript on Chrome? Thanks in advance. I have referenced the following thread for ideas on the issue I want solved, but only took it as far as I can. Any help would be great. http://codingforums.com/showthread.php?t=202459 I would like to utilize this script where I could pass the string of words to another page. Meaning, search for the text, actually a word, then take the two words following the searched text and have them passed to the next page...I have tried to "alert" the words, but have no success. I have tried to modify the code using the following, but the result just posts a "-1" in my alert popup. As you can see I modified the code from the original thread in the third block of "for" code. also, I added an "alert" tag. One more thing, I added a function call for the form button. Hope you can help out. The code is below: Code: <script type="text/javascript">
var count = 0;
var itemList = new Array();
var oldText = "";

Join Chief Economist Mark Zandi and Director of Housing Economics Celia Chen for an introduction to Housing in Crisis: When Will Metro Markets Recover?, a new study that offers a comprehensive look at the near-term prospects for a recovery in housing markets in a recessionary environment. In addition, Dr. Zandi will critique the effectiveness of policy thus far in the housing crisis and discuss additional measures the Obama administration will enact that are assumed in the Moody's Economy.com house price forecast. Key findings:- In about 10% of metro areas, price declines will exceed 30%.
Economic experiments in virtual worlds (or, more generally, virtual economies) have been proposed a number of times and also conducted to some extent. A recent addition to the conducting category is Reciprocity and status in a virtual field experiment by Andreas Nicklisch and Tobias Salz. In their study, the authors conducted a field study in World of Warcraft, seeking to investigate the role of reciprocity, and the effect of status on reciprocity, in employment relations. Reciprocity here means the observed tendency to react kindly to kind actions, even though such reactions are not enforced. Unlike previous economic experiments conducted in virtual worlds, the authors did not create an artificial setup for the experiment. Below, I summarize and briefly discuss the study and its findings.

I have a Java Script that displays a Daily Affirmation on a webpage from an array of 365 Affirmations within the same html webpage file. This makes the html file size way too large. So I would like for the java script to read the array from an external text file on the same website server. Please provide me the Code to insert within my script which will read the array from an external text file - and also the format that the array of 365 lines must be typed into the external text file. I am not a Javascript Programmer - and know nothing about Javascript, so please write your reply at my (lack of) knowledge Level. Thank you in advance! Here is the code I am using. <script language=javascript> <!-- Date.prototype.getDOY = function() {var onejan = new Date(this.getFullYear(),0,1); return Math.ceil((this - onejan) / 86400000);} var today = new Date(); var DOY = today.getDOY(); var HL=new Array() //Configure the following array to hold the 365 HLs for each day of the year HL[1]='HL 1 goes here' HL[2]='HL 2 goes here' HL[3]='HL 3 goes here' // Jump to Day 224 of the year for this example only HL[224]='I am surrounding myself with positive and supportive people. When I nurture relationships that give me energy and enjoyment, I mirror my beliefs that I deserve such gifts.' HL[225]='Today I affirm my own worth and value, and discover that the world agrees with me.' HL[226]='I am sowing seeds based on a healthy belief in my own self-worth. My life is flourishing with growing love, contentment, and exciting possibilities.'

Hi all - I'm designing a website, and I need to have a search button allow users to search the inventory that is on the website. I'm not quite sure what code I'm going to use for the search button, but I imagine that I can work on that sometime.. Along with the code, am I required to have something such as a MySQL database set-up or something of the sort? This question may be mis-categorized, so please let me know if it is. Thanks everyone! Hi they all, I want make autocompleted searching for my site. I find HTML5 autocompleted script in google. I use Laravel and PHP and MongoDB. My script PHP Code for search autocompleted. PHP Code: publicfunction searchAutoCompleteAjax(){ $keyword =Input::get('keyword'); $result = array();if(!empty(trim($keyword))){ $mongoResult =MongoDB::instance(true)->collection("items")->like('name',$keyword)->limit(0,10)->fetch(); if($mongoResult){foreach($mongoResult as $key => $item){ $result[]= $item['name'];}}} echo json_encode(array("error"=>0,"message"=>"Success","result"=>$result));} I result 10 query PHP Code: $mongoResult =MongoDB::instance(true)->collection("items")->like('name',$keyword)->limit(0,10)->fetch(); My old javascript code and working for me. Hello, Could anyone help me? I'm looking for a script that remembers, re-sets, and can set to the previous state the show or hide behavior of a layer upon return to the page. I have an image gallery that's in 3 categories: wedding, bridal shower and save-the-dates. When viewing an image in the bridal shower or save-the date galleries and I press on the link I created titled "Back to Gallery" it does not return me back to the Bridal Shower or Save-the-dates gallery (whichever I'm in) it returns me to the main Invitations gallery page. So bascially I'm looking for a script that will write to a cookie what layers are shown and what are hidden so when you return it reads the cookie and displays the last layers you had showing before leaving the page. All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero As of right now I have a code that will work in IE but wont work in FireFox...go figure. Basically what I want to have happen is when you type in an area code it will provide an output in a predetermined area of the page. For Example: Input- 512 Output - Austin, TX The code that I have doesn't work with firefox and I was just wondering if there was a code that would allow that to happen. Thanks! I can get this code to take two separate sections of a file which are not beside each other and write them into another file. It always comes up as a single full line of the code instead of the sections I want. The code includes the student number first name last name and three results of assignments. I want the code to write the student number and three results of all the students into a file and then work out the average of the student results. Can you help? Code: try{
while (in.hasNextLine())
{
String line = in.nextLine();
out.println( line);
int i=0;
if(!Character.isDigit(line.charAt(i))) { i++; }
studentStringNumber = line.substring(0, i);
String stringResult = line.substring(i);
studentStringNumber = studentStringNumber.trim();
stringResults = stringResults.trim();
double stringResultsValue = Double.parseDouble(stringResults.trim());
stringResults = in.nextLine();
studentStringNumber = in.nextLine();
studentNumber = Integer.parseInt(studentStringNumber);
if(in.hasNextInt())
{
int value = in.nextInt();
}
results = Double.parseDouble(stringResults);
if(in.hasNextDouble())
{
double value = in.nextDouble();
}
Scanner lineScanner = new Scanner(line);
studentStringNumber = lineScanner.next();
while(!lineScanner.hasNextDouble())
{
studentStringNumber = studentStringNumber+ " " +lineScanner.next();
}
stringResultsValue = lineScanner.nextDouble();
}
}
Does anyone know how to accomplish this? I got the html file to show but none of the text in the file will show.

Philp if you read this i am not asking for a javascript code i am asking wether or not it can be done. P.s if your a nice person like philp is not and you want to private message me if you have one I'm having major pains trying to figure this out. I'm kind of new to Javascript, I need to open a text file from an external server, store each line in an array, then search that array for a certain word (HIGH), and if it exists then write something to the webpage, and if not, write something else. Here is what I have so far: Code: <html>

//var highsearchreg = new RegExp("HIGH");
//var wxd1high = wxd1array[x].search(highsearchreg);

When added to a webpage, nothing shows up except the "Hi!" and there are no errors in the Javascript Console in Google Chrome. Is this possible with Javascript, and if so, what am I doing wrong or not doing? Also, I have 2 URLs, one is a text file that has the HIGH text I want for an example, the other is the current file, which shouldn't have HIGH in it (unless the weather in the US turns really bad) Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. |
